PlaceboPlaceboParticipants received Placebo intravenously (IV) or subcutaneously (SC) every 4 weeks (Q4W). Any participant in the placebo arm who was considered a non-responder at Week 12 received 900 mg Mirikizumab IV Q4W for 3 doses, then 300 mg SC Q4W for the remainder of the study. Nonresponse is defined as failing to achieve at least a 30% decrease in stool frequency (SF) and/or abdominal pain (AP) and be no worse than baseline.

Primary Outcome Measures
NameTimeMethod
Percentage of Adult Participants Achieving Clinical Response at Week 12 and Endoscopic Response at Week 52 (Placebo and Mirikizumab)Week 12 to Week 52

Clinical response by patient reported outcome (PRO) defined as ≥30% decrease in stool frequency (SF) and/or abdominal pain (AP) \& neither score worse than baseline. SF (number of liquid or very soft stools) as per Bristol Stool Scale Category 6 or 7 and AP (4-point scale: 0=none, 1=mild, 2=moderate, 3=severe).

Endoscopic response defined as ≥50% reduction from baseline in total Simple Endoscopic Score for Crohn's Disease (SES-CD) score. SES-CD evaluates 4 variables assessed in 5 bowel segments, each scored from 0-3: presence \& size of ulcers (none=0; diameter 0.1-0.5 cm=1; 0.5-2 cm=2; \>2 cm=3); extent of ulcerated surface (none=0; \<10%=1; 10% to 30%=2; \>30%=3); extent of affected surface (none=0; \<50%=1; 50% to 75%=2; \>75%=3); presence \& type of narrowing (none=0; single, can be passed=1; multiple, can be passed=2; cannot be passed=3). Total is sum of all scores across all bowel segments. Scores range from 0 to 56, with higher scores indicating more severe disease.

The IBDQ is a 32-item patient completed questionnaire that measures 4 aspects of patients' lives: symptoms directly related to the primary bowel disturbance, systemic symptoms, emotional function, and social function. Responses are graded on a 7-point Likert scale in which 7 denotes "not a problem at all" and 1 denotes "a very severe problem." IBDQ total score is calculated as the sum of all questions. Scores range from 32 to 224; a higher score indicates a better quality of life.
